Roanoke Crawl Spaces runs six core services — encapsulation ($6,000–$15,000), structural repair, waterproofing, vapor barriers, mold and moisture control, and drainage — sequenced water first, sealed second.
Start from the symptom you can actually see, and the page below has the local numbers behind it.
Crawl Space Encapsulation
The full seal-and-dry system, detailed for the pier field you actually have rather than a standard one.
Crawl Space Repair
Sistered joists, girder replacement and steel supports — common work in century-old stock on stone piers.
Crawl Space Waterproofing
For crawls taking water off the slope: intercepted uphill of the house, not mopped up underneath it.
Vapor Barrier Installation
Reinforced 12–20 mil ground liner, cut around irregular stone and block rather than trimmed to fit.
Mold & Moisture Control
Remediation for crawls that never get enough winter sun to dry, plus the fix that keeps growth away.
Sump Pump & Drainage
Collection at the footing line and a discharge routed with the fall of the lot in mind.
Cost Guide: Encapsulation Pricing
What moves the number in the valley — clearance, pier condition, and whether the slope is delivering water.
Sagging Floor Repair
Bounce over a damp bay, and the joist ends that have been sitting on wet stone.
What do the six services cost?

|---|---|---|
| Crawl space encapsulation | $6,000–$15,000 | 2–4 days |
| Structural repair | $1,500–$8,000 | 1–3 days |
| Waterproofing | $2,500–$7,000 | 1–2 days |
| Vapor barrier | $1,500–$4,000 | 1 day |
| Mold & moisture control | $1,500–$6,000 | 1–2 days |
| Sump & drainage | $1,500–$7,000 | 1–2 days |
Every range narrows to a written, itemized number after the free inspection — because on crawl work the honest quote requires eyes and readings under the actual house.
Why we ask when, before we ask what
Crawl work fails when it is done out of order: a liner over standing water, mould treatment in a crawl that is still damp, repairs underneath a leak nobody found. The sequence is water, then structure, then seal, then dry, because each stage protects the one after it.
In this valley there is a step before all of that, and it is a question about timing. Slope seeps run in spring and are gone by late summer, so the same crawl gives two different answers depending on the month you look. A scope written from an August reading can be entirely accurate and still address the wrong problem.
So the inspection reads history as well as moisture: stain lines on piers, silt fans, rust patterns on ductwork — the record of what happened while nobody was down there. On older pier-and-block crawls in Old Southwest and Raleigh Court that evidence is usually written plainly across the stone.
What happens after you book
- A same-business-day reply to get you scheduled, usually within two days
- The inspection — moisture readings, a structural check, and the crawl read for seasonal evidence
- The debrief — you see the readings and the pictures before any price is mentioned
- A written, itemised quote, honoured as written and staged if you want it staged
- Scheduled work, documented at each stage
If you are inspecting in late summer and the evidence says the crawl runs wet in spring, the quote says that too. It is better to know the scope was written for March than to find out in March.
Frequently asked questions
Which service do most Roanoke homes actually need?
It splits by aspect and slope more than by anything else. Houses taking water off the hill start with drainage; north-slope houses that simply never dry start with moisture control. Two identical houses a few hundred metres apart can need different things.
Can the stages be combined into one project?
Usually they should be. Drainage, repair and sealing share one mobilisation and follow each other naturally. Quotes come itemised so you can still stage the work across budgets if you would rather.
Is there a wrong time of year to get inspected?
There is no wrong time of year to get inspected, but there is a wrong way to read one. Late summer shows the crawl at its driest, so the inspection looks for the evidence of the wet season rather than relying on the day's readings alone.
Do you work on crawls another company sealed?
Regularly. In older stock the common finding is a liner cut for a modern crawl and fitted to a century-old stone pier field, where it has lifted. The inspection reports what is there, including when it only needs finishing properly.
Not sure which page fits your problem?
Musty smell points to moisture control; water points to waterproofing; bouncy floors point to repair; wanting it fixed for good points to encapsulation. Or skip the sorting — the free inspection diagnoses it under the actual house, across nine communities.
